The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...
Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...
Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...
An op amp-based amplifier design overcomes errors associated with resistive current sensing, particularly those resulting from high commonmode voltages. Many current-sensing ICs are available for ...
